Abstract

The invention provides a civil defense alarm control system based on PDT digital trunking. The system comprises a PDT digital trunking communication network, a plurality of control centers, a plurality of area stations and a plurality of alarm stations connected with one another. The civil defense alarm control system based on PDT digital trunking provided by the invention is good in performance, high in security and low in cost; and according to the system, multiple communication methods are backup for one another and interconnected, so that a system coverage range and system availability are improved.

Description

technical field [0001] The invention relates to a PDT digital cluster-based civil air defense alarm control system, which belongs to the field of civil air defense alarm systems. Background technique [0002] The air defense and disaster prevention alarm system is an important part of the national defense system and emergency management system. Its working conditions directly affect the country's war potential and people's lives and property safety. Its reliability and safety are very important. At present, air defense and disaster prevention warning systems usually use dedicated ultrashort wave wireless networks and IP networks to transmit pictures, texts, videos, locations, data and other information. [0003] When individual devices in the ultrashort wave wireless network fail and are in a continuous transmission state, it will cause part or even the entire network to fail to communicate normally; the same-frequency and adjacent-frequency interference in ultrashort wave w...
